Challenges latch-bridge model in animal smooth muscle; leaves open relevance to intact or human physiology.
The observation that high levels of tension generated at low levels of light-chain phosphorylation are associated with high levels of ATPase activity challenges the latch-bridge model of smooth muscle contraction.
Kenney et al. (1990) studied this question.
